OS Therapies Makes Strides in Cancer Treatment

OS Therapies (NYSE American: OSTX), a forward-thinking company in the immunotherapy and biopharmaceutical field, has recently announced the exciting development of two new antibody drug conjugate (ADC) therapeutic candidates. Utilizing its unique SiLinker™ technology, the company is set to enhance treatment options for various forms of cancer including Breast, Lung, Gastric, Ovarian, and certain uncommon cancers that affect the Fallopian tube and peritoneum.

Innovative Technology Behind New Therapeutic Candidates

The newly developed candidates represent a significant leap in the fight against cancer. OS Therapies has confirmed their potential via rigorous target engagement tests. The ongoing commitment to refine and advance the tADC platform will position the company as a leader in this domain. Additionally, the Company aims to license select therapeutic candidates to enhance the pipelines of strategic partners, particularly focusing on the pH-sensitive SiLinker™ component.

Proof of Concept and Future Prospects

Demonstrating considerable progress, OS Therapies' initial tADC asset, OST-tADC-FR?-H, has successfully shown proof of concept in preclinical models targeting ovarian cancer. With the introduction of two additional constructs into the pipeline, the Company is well-equipped to play a vital role in the landscape of therapeutic product development, delivering innovative solutions to partners in need.

Commitment to Internal Projects

Despite the focus on external partnerships, OS Therapies remains dedicated to in-house projects. The company's ongoing development of the OST-HER2 immunotherapy cancer vaccine platform is designed for both canines affected by osteosarcoma and human patients facing similar challenges. This approach not only underscores the company's versatility but also its commitment to pushing boundaries in cancer treatment.

Leading the Charge Against Osteosarcoma

As a clinical-stage company, OS Therapies attentively focuses on the identification and commercialization of treatments for osteosarcoma and other solid tumors. The lead asset, OST-HER2, works by harnessing the immune-stimulatory properties of Listeria bacteria to incite a robust immune reaction toward the HER2 protein. This innovative approach has led to the completion of a 41-patient Phase 2b clinical trial for OST-HER2, with data anticipated in the near future, and a prior Phase 1 trial in breast cancer showcasing encouraging preclinical results.

Advancing Antibody Drug Conjugate Platforms

The Company is also expanding its next-generation ADC platform, aptly named tunable ADC (tADC). This cutting-edge technology features customizable antibody-linker-payload combinations, enabling a versatile approach to treatment. By utilizing its proprietary silicone linker technology, OS Therapies consistently innovates, equipping the oncological landscape with multiple payload delivery solutions.
